The “optical imaging technology” (Bachman, 1986) was the best materials system of its time for fabricating “photodiode arrays” (Bachman, 1986) that were used in NASA’s satellite system. Bachman considered this to be just the beginning of experimentation with microgravity for the production of semiconductors. He articulated the need for further advances in physics to improve the photoconductive properties of the detectors in order to improve the quality of the satelites
Twenty years later Bachman’s optical imaging device is being applied to identify diseases, as well as, analize the chemical and biological properties of different cystals and alloys in vortex chambers. The photoconductive device described in the study offers a cost effective method of fabricating biochips when coupled with simulation software known as Comsol software.Industries outside of quasi-government agencies such as NASA are utilizing microgravity technology. The budgets of these industries are not limitless, and therefore are in need of a feasible way of applying the quantum leap in semiconductor quality that is due to the microgravity science, without incurring the considerable costs that would keep them out of the field of biotechnology.
The model described in this study offers theoretical outcomes when describing modified conditions calculated in simulation software as well as the actual observed events that occur within the various chambers of the photoconductive device. The properties that were observed utilizing simulated fluidic vortex chamber device are fluid flow, concentration and diffusion, and electrical conductivity. The conditions that were modified were velocity of fluid flow, locations of fluid concentration, and length of time the fluid would be concentrated at various locations. The results that the changing conditions as described in the “incompressible Navier-Stoke equation”.
